I noted that for all Power Registers, Watt is Declared as Unit.

S- Should be VA
Q- Should be var
P- Should be W

Hi, I did some testing on a TS-65a Meter

My setup was
A Meter and conditions readout via ESP Home,
Then I tried different loads to figure out the missing registers,

My loads

• 60W Light bulb (Resistive Load)
• 600W VacumCleaner (Inductive Load)

With the test, I Figured out that
I'm pretty certain that this is 262..263 is PowerReal_P_Sum - 0.1W.

About 90% certain that 268..269 - Power Factor Sum - 0.001deg

And this 270..271 read always zero. So I have no Clue, maybe - Current_AC_Sum -

Hi,
First, many thanks for sharing this repo.
Where the heck did you find this information?

I'm looking for the same kind of thing for their newer smart meter TS100a. Reset or state register is what I'm after. I don't dare to spam the registers with write commands just to figure out which ones are the writable ones.
In my dreams I also see a complete list with descriptions, and such.
